“The militant leaders in the North Caucasus are trying to destabilize the already complicated situation in Dagestan,” the special service officer added.

The train was on its way from the Azerbaijani capital of Baku to Moscow when several cars ran off the track. A fire allegedly broke out but was extinguished shortly after the accident. No injuries have been reported so far.

The railway is now being checked for explosive devices. The derailment has caused delays on the railway, in particular to a passenger train with over 100 people aboard.
